In this example where the initial position and velocity were zero, the height of the position curve is a measure of the area under the velocity curve. The height of the position curve will increase so long as the velocity is constant. As the velocity becomes negative, the position curve drops as the net positive area under the velocity curve decreases. Likewise the height of the velocity curve is a measure of the area under the acceleration curve. The fact that the final velocity is zero is an indication that the positive and negative contributions were equal.
